FEED-WATER REGULATOR FOR BOILERS.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed June 28, 1910. Serial No. 569,369.

To all whom it may concern:

Be it known that I, MARTIN BALAZIK, a

l 1 citizen of the United States of America, re-

siding at Republic, in the county of Fayette and State of Pennsylvania,have invented certain new and useful Improvements in Feedater Regulatorsfor Boilers, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates. to a feed water regulator for boilers, and theobject of the invention is to provide a regulator for boilers that ispositive in operation, strong and durable, free from injury by ordinaryuse, applicable to various types of boilers, and efficient for thepurposes for which it is intended.

I attain the above object by utilizing a suitable supply of steam, afloat-actuated valve for controlling the supply of steam, a pistonadapted to be moved by said steam, and a slide valve actuated by saidpiston and adapted to control the supply of water to the boiler. Allthese parts arecompactly arranged upon the top of the boiler and are aapted to cooperate in maintaining a pre-described quantity of waterwithin a' boiler. The invention will be hereinafter specificallydescribed and then claimed, and reference will now be had to thedrawings forming apart of this specification,wherein: Flgure 1 is anelevation of the regulator mounted upon the boiler, the regulator andboiler being partly broken away and partly in section. Fig. 2 is alongitudinal sectional i Fig. 3 is a cross sectional view taken on theline III-III of Fig. 1, and Fig. 4 is a similar view taken on L view ofthe regulator.

the line IVIV of Fig. 2.

In the accompanying drawings the reference numeral 1 denotes a portionof the top of a boiler having an oblong opening 2 covered by a dome 3.

4 denotes an elevated platform having legs 5 secured to the top of thedome 3, as at 6. The platform 4 is provided with a central opening 7 andwith another opening 8 located adjacent to the end of said platform. I

9 denotes a cylinder secured upon the platform 4, as at 10, and in thiscylinder is movably arranged a piston 11 having the piston rod 12thereof extending'through a stufling box 13 carried by one of the heads14 of the cylinder. The head 14 is provided with a recess 15 for acompression spring 16 encircling the piston rod 12 between the head 14and the piston 11. The pistonhead 17 of the cylinder is provided with acentral recess 18 in which is fixed the end convolution 19 of acompression spring 20, this. spring cooperating with the spring 16 incushioning a movement of the piston 11.

21 denotes 21 depending valve body carried by the cylinder 9 andextending through the opening 7. The valve body 21 is provided with abore 22 and the lower end of said bore is closed by a cap 23 mountedupon the end of the valve body 21. The cap 23 is provided with astuffing box 24 and extending through this stuffing box and anotherstufling box 25, carried by the dome 3 is a float rod 26. Adjustablyconnected to the lower end of the float rod 26 by a set screw 27 is anoblong flat float 28, said float 1 having a central opening throughwhich the rod 26 extends, whereby the float can be adjusted upon saidrod. Connected to the upper end of the float rod 26 within the valvebody 21 is a slide valve 29 having a by-path 30 formed in one sidethereof, said by-path alternately establishing communication betweenports 31, 32, and an exhaust port 33, these ports being formed inalinement in the wall of the valve body 21. The port 31 is connected toone end of the cylinder 9 by a pipe 34 and the port 32 is connected tothe opposite end of the cylinder by a pipe 35. The wall of the valvebody 21 opposite the exhaust port 33 is provided with a steam inlet port36, the inner end of said port terminating in a longitudinal groove 37formed in the inner wall of the valve body 21, while the outer end ofthe port 36 is connected by a pipe 38 to the dome 3, to receive steamfrom the top part of the boiler.

39 denotes a chest mounted upon the elevated platform 4, said chesthaving a depending portion 40 extending through the opening 8 of saidplatform. The depending portion 40 and the bottom of the chest 39 areprovided with a vertical port 41 and the lower end of said port isconnected by a pipe 42 with the top part of the boiler 1, while theupper end of the port terminates in the chest 39. The chest 39 is closedby a lid 43 and the wall thereof is provided with an opening 44connecting with a Water supply pipe 45. Slidably mounted in the chest 39is a slide valve 46 connected to a ends of the rods 12 and 47 areloosely connected, as at 49, to levers 50 pivotally connected, as at 51,to extensions 52 of the platform 4. The upper ends of the levers 50 arepivotally connected together, as at 53, by a connecting bar 54.

As shown in Fig. 2 of the drawings the float is in its lowest positionand the boiler 1 is taking water from the pipe 45 through the chest 39,port 41, and pipe 42, and the steam admitted to the valve body 21through the pipe 38 is also admitted to the cylinder 9 through the pipe34, retaining the piston 11 in the position shown in Fig. 2.

When the float 28 is raised, asshown in Fig. 1 of the drawings, thesteam passing through the pipe 34 passes through the valve body 21, pipe35 to the cylinder 9 and forces the piston 11 into engagement with thespring 20 within said cylinder. This movement of the piston shifts thelevers 50 in the slide valve 46, which closes the upper end of the port41 and prevents the water from entering the boiler 1. When the cylinder9 is taking steam at the forward end thereof the steam is exhausted fromthe rear end through the pipe 34, valve body 21, and exhaust port 33.The position of the float 28 upon the float rod 26 determines the levelof the water within the boiler.

What I claim, is:

1. A feed water regulator for steam boilers comprising the combinationwith a boiler provided with a dome, of a platform mounted upon the dome,a cylinder carried by said platform, a piston within said cylinder, afloat arranged in the boiler, a stem connected to the float andprojecting through the dome, means suspended from the cylinder andconnected to the stem and actuated by the float and in connection withthe cylinder admitting steam thereto to shift said piston, a chestcarried by the platform, a water supplyvpipe opening into said chest, awater feed pipe leading from the chest to the boiler to one side of thedome of the latter, a valve movably mounted in said chest for closingcommunication between the chest and the water feed pipe, thereby cuttingoff the supply of water to the boiler, and a pair of levers operativelyconnected with the piston and said valve and pivotally connected withopposite ends of said platform and further pivotally connectedtogetherfor shifting the piston and slide valve simultaneously in the samedirection with respect to each other, thereby controlling the watersupplied to the boiler.

2. A feed water regulator for steam boilers comprising the combinationwith a boiler provided with a dome, of a platform mounted upon the dome,a cylinder carried by said platform, a piston within said cylinder, afloat arranged in the boiler, a stem connected to the float andprojecting through the dome, means suspended from the cylinder andconnected to'the stem and actuated by the float and in connection. withthe cylinder admitting steam thereto to shift opposite ends of saidplatform and having pin and slot connections intermediate their endswith the piston and valve, and a connecting bar pivotally connected atits ends to the upper ends of the levers whereby the piston and valvewill be simultaneously actuated to control the supply of water to the"boiler.

In testimony whereof I affix my signature in the presence of twowitnesses.

MARTIN BALAZIK.
